This book intend to supply readers with some MATLAB codes for ?nite element analysis of solids and structures. After a short introduction to MATLAB, the book illustrates the ?nite element implementation of some problems by simple scripts and functions. The following problems are discussed: - Discrete systems, such as springs and bars - Beams and frames in bending in 2D and 3D - Plane stress problems - Plates in bending - Free vibration of Timoshenko beams and Mindlin plates, including laminated composites - Buckling of Timoshenko beams and Mindlin plates The book does not intends to give a...
